We report a case of IMT coexisting with colon cancer the first case of its kind, to our knowledge, reported in Japan. An 89-year-old woman with fever, anemia, and an inflammatory hematological test response was diagnosed with carcinoma by colonoscopy, necessitating right colon resection. The histopathological diagnosis was both moderately differentiated tubular adenocarcinoma and inflammatory myofibroblastic tumor (IMT). The fever and inflammatory response both improved after operation, so we concluded that IMT was related to these symptoms.

Key words
